To 1 un /om it may (rum-c172 lloit known that l, 'lnonms S. l'iOMANS, acitizen of the United States, residing at llelnpstentl, in the county ofNassau and State of New York, have invented new and usct'ul Improvementsin Keyboard Mechanism t'or Linc-Composing Machines, of which thefollowing is a specification.

The present invention relates to improvements in line composing machinesand more especially to those of the Well known linotype class, and theinvention pertains to the keyboard mechanism whereby manipulation of thelinger keys thereof controls the actuation of power-operated cam -y0keswhich cam yoltes transmit corresponding movements to escapemcnt devices,the latter controlling the delivery of matrices from differentmatrixcontaining channels of the magazine.

'lhe prinmryobject of the invention is to provide novel and improvedbearings for the cam yokes, such bearings enabling any one '01 more ofthe yokes to be removed, together with its individual or respectivebearing, from the machine for any purpose, stich tor example, aslubrication, cleaning or repairing', the removal of one 'or more of thecam yokes not affecting the remaining cam yokes.

To this end, the invention consists in certain in'iprovements, andcombinations and arrangements of parts, all '18 will behereinafter morefully described, the novel fentures being pointed out particularly inthe claims at the end of the specification.

In the accompanying drawing-Figure 1 is a perspective view of a sectionof the keyboard mechanism of a machine constructed in accordance withthe present invention, it being understood that only a few of the op-verntive parts of the keyboard mechanism are shown; Fi 2 is a perspectiveview showing another method of holding the cam yoke hearings inoperative position.

Similar parts are designated by the same reference characters in theseveral views.

The present invention is applicable genere-11y to any style of machineemploying a keyboard of this class, and it is to be understood that theclaims at, the end oi"? this specification are not limited'to a machineof any particular type, although the invention its respective hearing.in

tending-teeth or projections 13 is illustrated and will he described assip plied to keyboard mechanism of the same type as that disclosed in myprior applicaon Serial No. 707,926 filed July 5, 1912. is the presentinstance 1 designates z i of the key levers of the keyboard, these ylovers being, usually pivoted. shown, nd provided at their forward endswith finger keys which are adapted to he manipulated in the usual way bythe fingers of the operator. T he rear ends of the k 1 leversoperatively connected to correspcnding tically movable key bars 2, thelatter being suitably guided'in the frame of the and are lifted when thecorrespor keys are depressed. Ther 'h operate with corresponding triglatter being mounted to rock on the pivot pin st supported by the frameoi the ins; chine, each trigger having a snhst ntiaily horizontal armwhich cooperates with the respective key her and vertical or np- Wardlyprojecting arm which controls the operation of the respective yoke. Thecom yokes 5 may of the usual or anyde sired construction, although thepresent in vention provides improved pivottl he therefor.- According' tothe tion, an individual hezirir 6 each cam o each preferably with a slotT to its cor responding'end of the respe earn yoke and a pivot pin 8 isprovided h tch forms a pivotal connectizn between each yoke theconstruct-ion shown, each hearing has a lower reduced portion formingasha-nlt'z l which may cylindrical so as to tit removehly in a boreformed in a stationary supporting bar 10, the bearings for the differentyokes in the present instance being arranged in a longitudina'lrovv inthe bar 10 and may be insorted and removed from the top thereof. The camyokes carry cams 11 which. in the present instance, are pivoted torotate in hollow chambers 12- in the yolies and these cams are arrangedabove a continuously revolving powernperated roller The cams areprovided with pins or projections is and :2 bar 15 is fixed. to the stii 'ra mework 16 and provides doivnvvs which the projections 14. on therespective cams normally rest, lhe cams being thcreby held out ofContact With the surface of the revolving roller 13.

The triggers 3 normally SBPPOI'I'J the cam yokes in such positions thattoo prcjccslons 14- on the cams will rest against the beetle orprojections 1?, the cams at this time being out of contact with therevolving roller and Eunice the will be inactive. Beyrcssmn of any oneof the fingor keys of the lzy"- board, however, will cause upwardmovemetal; of the corresponding key oar and'fl aji: leer will track thecormspondingcrigger Elmto a posifiion -where its upwardly extendling armmoves from beneath the correspond ing cam ego and into the hollowportion llzoreci', t lei-oily allowing such com yolio cc drop anddropping of time com yoke will carry llae' projection loci therespective corn downwardly and col; of contact will the respcciive:oooih or projection 17 end will cons-e chc respective com to Erosiontop of the revolving roller. The rcvolvin Lnooil on of the roller willthen cause ZG'l-fiilfifi of is com and tho com is so shaped tho-i whencombed it elevate the cam yolrc. The upward movement of the com yokeunder the action of its cam is imnsmited by suit ablc means to thecscapement which controls the delive. of corresponding matrices from themagazine, plan-gem 18 being shown in the present instance which operatevertically through guides 19 filled in the frame memos? 20, and i .131831 ends of these 131cm gors cooperate v.53; 1 vertically movablereeds 23, the r o ooraing in the usual or suitable 3.113011 thematrix-controlling eseapements. After each cam has actuated its com yoketo efiec'iz lo delivery of the selooted matrix from the magazine, suchcam returns to a position where. its projcction lowest-s against thecorresponding tooth or projection 1'3, the cam being; then out ofcontact with the revolving roller and the cam will rcsl upon its triggilce'latter being resl ored to normal osztion when ocessure upon thecomes on log finger key llas been relieved by the operalcr.

Means is provided for retaining the bearlogs for the com yokec properoperative ocsition allhough enobli any one or more of these bearings toL Wsily quickly removed tog ether its com yoke and cam when such is doliable on necessary. In Fig. 1, cigar or keeper 22 is providod, it beingpivotzllly supported in any suitable way, such, for example, as by thopin or rod 23 carried lyv the framework 16, a stop is pro- L.' z .8 1 vvided' for suppo Wong into on 'tion indicated by the dotted lines inFig. l,

ings being thereby held in their normal operative positions. When it isdesirable or neccssar to remove any one of the cam yokes, e keeper isswung out of its operafive position and, for example, into. the post thekeeper then resting against the stop '24 and any one or more. of thebearings can be lifted or removed from the bar 10. Return of the keeperto the full-lineposition locks ell vthe bearings in position. Instead ofusing 2. be! or keeper such as that just dcscribed for retaining thebearings in place, other meansmay housed, such, for example as shown inFig. 2,"'whe'rein' set-screws 25 coiiperatowith the stems or shanks ofthe corresponding bearings and thereby retain 52cm in the b52219.

Tho present invention provides simple and improved-moans whoreb' anyoneor more. of the cam yokcs may eeasily and quickly removed and replacedand in c; Floyinig removable cam yoke bearings emaodying the presentinvention, it I is, unnecessazy to slot or otherwise cut away anyportion of the pivot bearing in the cam yoke and hence such bearing iscapable of withstanding wear'to the best advantage.-. v
